Why in Boxing/MMA, does the timer disappear in the last 10 seconds. | That's because the clock on screen is not the "official" clock.

How can the probabilities of all possible outcomes of an event not sum up to one? In other words, how can there exist a process for which unitarity doesn't apply? | > However, the physicists who came up with the model postulated that locality and unitarity do not hold true at the quantum level. No, that's not correct. They have a different mathematical formulation where unitarity and locality emerges from first principles. The end result is very much unitary |
Why (near) perpetual motion car is not possible. | Solar power is the only promising possibility, as you're taking "free" energy from the sun and converting it to useable power. But isn't very efficient yet, and the needed components add noticeable weight. Thus the charging rate of a car completely covered in solar panels still isn't enough to power the motors to move ... |

Why are steel surfaces relatively inhospitable to bacteria and other germs whereas stuff like acrylic are not? | I believe it has to do with the surface and how porous it is/isn't.

Why can schools ban peanuts but not enforce manditory immunizations? | "Do this" is harder to enforce than "Don't do this"Because the loudest parents are often the dumbestI would like to see exemptions for those with strongly held beliefs that peanut butter is the best for lunch.On the whole, in schools, the squeakiest wheel gets the oil. And by wheel, I mean parents. Schools have to bend... |

Her brain tries to process an... |
Why cold water tastes better? | I don't think it has to do with the taste -- I think it has to do with the refreshment. Humans don't drink water because it tastes good, but rather because we need it to survive and cool down when we begin to overheat. Since cold water is so refreshing, it's more enjoyable to drink. When a drink is more enjoyable, one ... |
What is a transistor, and why was it's invention so revolutionary? | Transistors replaced vacuum tubes, which perform the same function: they both can take a small electrical current and use it to control a larger current. Both of them can be used as switches to perform on- and off- operations or as amplifiers. Amplifiers are needed for radios, TV's and so on. The big difference is that... |
If the FBI supercomputer would take centuries to crack a certain password, can't they build several replicas of it and then solve it faster with cluster processing? | First of all, all modern supercomputers are actually clusters of relatively slow processors.

Why places like fast-food chains support either Coke or Pepsi, but not both. | With big chains Coke or Pepsi will try to get an exclusive contract, and they'll make an offer to sell really cheaply.

Restaurants and chains generally have an ... |
Why can women have multiple orgasms while men can only have one? | Wow, I think these comments are way off the mark. Do you guys think that cavemen were running trains on the cavewomen?

Also, human females are better with a singl... |
Why do some people need to get up in the night and use the bathroom? Isn't that slowed down during sleep? | "Slowed down" is not the same as "turned off".

What is happening when my computer, or phone, says I'm connected to the Internet, but it won't load any internet pages? | Depends on what device and how they detect "the internet".

how did vanilla become the "generic" flavor | I'm just guessing, but I'd think that it's because Vanilla is such a strong flavour you only need a little bit of it, and because of that it doesn't impart much of a color to the food.

Why cross platform gaming isnt a thing. Like pc to xbox or ps4 multiplayer.

This is extremely noticable with strategy games shooters, but also comes into play with, for example, 3rd person action games. This means that it is very dificult to have a game that is exactly balanced between the differ... |
Why does the north star never move but all the other stars do? | The others appear to move because the earth is spinning on its axis.

How can we so distinctly remember things that never actually happened? | It is possible to vividly imagine something and then simply re-categorize that mental image as a memory rather than something you imagined.
